Preface
This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1.Structure and Drafting Rules of Standardization Documents"
Drafting.
This document replaces GB/T 19590-2011 "Nano Calcium Carbonate". Compared with GB/T 19590-2011, except for structural adjustment and editing
In addition to the modifications, the main technical changes are as follows.
a) Added index requirements determined based on particle morphology (see Table 1);
b) Changed the main content, average particle size, and specific surface area indicators of nano-calcium carbonate (see Table 1, Table 1 of the.2011 version);
c) Added magnesium and iron content indicators and test methods (see Table 1, 6.5, 6.6);
d) The indicators and test methods of grain size and agglomeration index are deleted (see Tables 1, 6.5, and 6.7 of the.2011 version);
e) The average particle size test method has been changed (see 6.2, 6.4 of the.2011 edition).
